兩個RadioGroups只有一個選定的RadioButton在他們每個人中

我的佈局中有兩個RadioGroups。我希望在RadioGroup中每次只檢查一個RadioButton。我嘗試了很多方法，但都沒有正常工作。現在我可以檢查RadioGroups中的每個RadioButton。兩個RadioGroups只有一個選定的RadioButton在他們每個人中

public class MainActivity extends ActionBarActivity implements View.OnClickListener, RadioGroup.OnCheckedChangeListener { 

String x; 
char y; 

int c=1; 

String num,n,type; 
int d,b,o,h; 
String dec,bin,hex,oct; 

EditText number; 
EditText result; 

Button convert, clear; 
RadioGroup rgFrom, rgTO; 
int convertedResult; 
int from=R.id.r10From; 
int to=R.id.r2TO; 

String stNumber; //Liczba przed przeliczeniem - string 
int numbResult; //Już int 

String iterResult; //Liczba po przeliczeniu - string 
int convResult; //Już int 

//int id = ((RadioGroup).findViewById(R.id.rgFrom)).getCheckedRadioButtonId(); 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    initialize(); 


} 

private void initialize() { 
    number = (EditText) findViewById(R.id.etNumber); 
    result = (EditText) findViewById(R.id.etResult); 

    convert = (Button) findViewById(R.id.bCalculate); 
    clear = (Button) findViewById(R.id.bReset); 

    convert.setOnClickListener(this); 
    clear.setOnClickListener(this); 

    rgFrom = (RadioGroup) findViewById(R.id.rgFrom); 
    rgTO = (RadioGroup) findViewById(R.id.rgTO); 


    rgFrom.setOnCheckedChangeListener(this); 
    rgTO.setOnCheckedChangeListener(this); 
} 


@Override 
public void onClick(View view) { 
    // from = (String)findViewById(R.id.rgFrom).getSelectedItem(); 
    // int id = ((RadioGroup)findViewById(R.id.rgFrom)).getCheckedRadioButtonId(); 
    //from = getFrom(id); 

    switch (view.getId()){ 
     case R.id.r2From: 
      from = rgFrom.getCheckedRadioButtonId(); 
      break; 
     case R.id.r8From: 
      from = rgFrom.getCheckedRadioButtonId(); 
      break; 
     case R.id.r10From: 
      from = rgFrom.getCheckedRadioButtonId(); 
      break; 
     case R.id.r16From: 
      from = rgFrom.getCheckedRadioButtonId(); 
      break; 
     case R.id.r2TO: 
      to = rgTO.getCheckedRadioButtonId(); 
      break; 
     case R.id.r8TO: 
      to = rgTO.getCheckedRadioButtonId(); 
      break; 
     case R.id.r10TO: 
      to = rgTO.getCheckedRadioButtonId(); 
      break; 
     case R.id.r16TO: 
      to = rgTO.getCheckedRadioButtonId(); 
      break; 
     case R.id.bCalculate: 
      stNumber = number.getText().toString(); 
      //iterResult = result.getText().toString(); 
      //calculate(); 
      break; 
     case R.id.bReset: 
      //reset(); 
      break; 
    } 
} 
@Override 
public void onCheckedChanged(RadioGroup rgFrom, int i) { 
    switch (view.getId()){ 
     case R.id.r2From: 
      from = rgFrom.getCheckedRadioButtonId(); 
      break; 
     case R.id.r8From: 
      from = rgFrom.getCheckedRadioButtonId(); 
      break; 
     case R.id.r10From: 
      from = rgFrom.getCheckedRadioButtonId(); 
      break; 
     case R.id.r16From: 
      from = rgFrom.getCheckedRadioButtonId(); 
      break; 
     case R.id.r2TO: 
      to = rgTO.getCheckedRadioButtonId(); 
      break; 
     case R.id.r8TO: 
      to = rgTO.getCheckedRadioButtonId(); 
      break; 
     case R.id.r10TO: 
      to = rgTO.getCheckedRadioButtonId(); 
      break; 
     case R.id.r16TO: 
      to = rgTO.getCheckedRadioButtonId(); 
      break; 
    } 
    } 
}

也許這會有幫助嗎？ http://www.mkyong.com/android/android-radio-buttons-example/ – anonymous

你的RadioGroups都包含一個RelativeLayout（兩次相同的錯誤）......爲什麼？儘快將其刪除。 –

謝謝，它的工作原理。但是我怎麼能創建類似於我的RelativeLayout的東西呢？ –

從RadiGroup取出RelativeLayout。因此，代碼會看起來像：

<RadioGroup 
    android:id="@+id/rgFrom" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_marginTop="10dp" 
    android:weightSum="100" > 

    <RadioButton 
     android:id="@+id/r2From" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_weight="50" 
     android:text="dwa" /> 

    <RadioButton 
     android:id="@+id/r8From" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginRight="75dp" 
     android:text="osiem" /> 

    <RadioButton 
     android:id="@+id/r10From" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:checked="true" 
     android:text="dziesiec" /> 

    <RadioButton 
     android:id="@+id/r16From" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="szesnascie" /> 
</RadioGroup>

這將解決你所面對約同組正在檢查多個按鈕的問題。但是，這會在UI中造成一個小問題。我想你想在一行中使用2個按鈕，而在另一行中使用另外兩個按鈕。據我所知，你必須實現你自己的自定義佈局。詳情請查詢this post。也請檢查here。希望它有一點幫助。
